Even by Harrop's standards this is particularly despicable.
A couple of TRAs engaged in a twitter discussion saying that Caroline Farrow looks like a man (because saying a transwoman looks like a man when they do is a hate crime but saying a woman does when they don't is banter). And this led to a conversation that there are compromising photos of Farrow.
Harrop then joined the discussion, implying that he has seen these photos and will send them to anyone who asks via direct message. This is in breach of revenge porn legislation and the ethics of being a doctor.
Farrow called the police last night over this harassment - but Harrop seems to have got worse and has tweeted that he's tracking her menstrual cycle
